Avaliação do controle postural e do sistema vestíbulo-oculomotor em atletas de tiro da modalidade pistola

Abstract

The shooting sports practitioners in developing skills such as dexterity, concentration and balance. The shooter needs to motor control and psychological foundations for the implementation of this sport. The stability of the athlete depends on the strength of shot against internal and external disturbances that affect their balance. This study aimed to evaluate the postural control and vestibule-ocular system athletes pistol shooters and verify their relationships with the athletic experience of volunteers. This descriptive analysis was institutionally approved by the IRB. We evaluated eight athletes of the sport pistol with a mean age of 37 years (sd ± 8.11), affiliated to the Confederation of Shooting and residents in the city of Rio de Janeiro. For data collection, was used to record socio demographic; videonistagmoscopia computerized system; stabilometry associated with a simulator of shooting and athletic experience questionnaire ACSI-28BR. Statistical analysis was performed using ANOVA and Post hoc. How relevant demographic results showed that all subjects were right-handed, half of them shoots with both eyes open; 14 years (sd ± 9) and mean time practice in shooting and an average of 14 hours (sd ± 13) of weekly training. Half of reported injuries associated with the shot. The ACSI-28BR coping indicated average of 39.7 (sd± 7.3) points among athletes. In correlation was observed only at speeds anteroposterior and medio-lateral. There was no significant correlation between data stabilometric, sociodemographic parameters and ACSI-28BR. At videonystagmoscopy, no athlete showed pathological change, physiological findings only as corrective saccades, delayed vestibulo-ocular reflex and horizontal nystagmus in 3 athletes, respectively. It was concluded that the shooters have postural control with significant changes only for the speed of displacement of center of pressure in the directions anteroposterior and mediolateral. The vestibulo-oculomotor system presented no functional changes to all the volunteers and showed no correlation with postural control despite the physiological findings to the MSQ (Motion Sensitivity Quotient). The athletic experience was not related to postural control of the shooters, however, the data suggest a high risk of injury associated with gunshot.
